Jaeger-LeCoultre Master Ultra Thin Date

Jaeger-LeCoultre has been building ultra-thin movements since the 1907 calibre 145, at 1.38mm still among the thinnest ever made, and the Master Ultra Thin is the modern inheritance. The case is slim enough to vanish under a cuff, and the dial carries only what it needs: applied indexes, dauphine hands, a date that sits without disrupting the symmetry. The manufacture calibre is made entirely in the Vallée de Joux.
